Information technology infrastructure includes networks; management and provisioning of large-scale computing, electronic data interchange and shared databases, and research and development to identify emerging technologies (Davenport et al. 1989). Almost two-thirds of the information technology budget of an organization is spent on information technology infrastructure (Weill & Broadbent 1998), not only to enable the sharing of information across different departments but also to provide flexibility to respond to changes in business strategy (Weill et al. 2002). Adequate investment and management of information technology infrastructure are the foundation of information technology adoption.
